Student Review (Not based on classroom experience) Reviewer: Deatra, Dec 6 2005 06:30:32:863PM |

Review based on: I discovered this tool because I was looking for some resources I could use in a project I am doing on how to find the area of a regular polygon. I just did a search in the Math Tools library for "polygon area." |

Appropriate for: practice of skills and understandings |

Other Comments: This tool visually illustrates the idea of how area changes as the number of sides of the polygon changes. |

What math does one need to know to use the resource? Formula for area of a triangle. |

What hardware expertise does one need to learn to use the resource? Geometer's Sketchpad |

What extra things must be done to make it work? You just download the Sketchpad file. You must have GSP on your computer in order for it to work effectively. |

How hard was it for you to learn? Easy |

Explanation: I just opened up the file and clicked on the links and it worked. There were no advanced steps that I had to try or work into. |

Ability to meet my goals: Effective |
